Technical audit

Tech-debt score, architectural risks, cloud costs, security gaps, AI quick wins and a 90-day roadmap you can execute with or without us.

Duration
2 weeks
Who for
Product teams with a PHP, Symfony, Node.js, JavaScript or Angular system that slows delivery, and a CTO who wants numbers before decisions.
How it starts
Read-only access to code and infrastructure, two interviews with the team, NDA if you want one.

What changes for youYou know what state the system is in, what it risks and what is worth doing first, before you spend on anything else.

What you get

  • Tech-debt score per module, with what hurts most
  • Map of architectural risks and single points of failure
  • Cloud costs: where the money goes and what can be cut safely
  • Security and compliance gaps, prioritized
  • AI quick wins: where tests, documentation and review can be automated next week
  • Upgrade and migration plan, plus a 90-day roadmap, executable with or without us

From a mixed PHP and Node.js stack to Symfony 7, with behavioral parity

A product used by large companies, moved to a modern foundation piece by piece, without users noticing.

Clusters and databases moved between AWS, Azure and Google Cloud, in production

Live production moved from AWS to Azure in two weeks, with about five minutes of downtime.

How we work

Four rules that have kept us away from failed rewrites and 3 a.m. incidents.

01

Incremental beats rewrite

We moved a production SaaS platform from a mixed PHP and Node.js stack to Symfony 7, with verified behavioral parity, while the product kept shipping. We recommend a rewrite only when the audit numbers actually support it.

02

Tests go in before the refactor

We document existing behavior, generate and verify tests, then change things. Nothing reaches production without the safety net.

03

AI orchestrated, human judgment

We use AI agents daily, including multi-agent setups, for tests, review, migrations and documentation. They compress delivery time. Architecture, decisions and accountability stay human, and we answer for every change that reaches production.

04

Boring on purpose

Clean architecture, small units, unexciting technology that keeps working. We write code as if someone else maintains it tomorrow, because that is exactly what will happen.
